I would like to test this, it looks rather nice.
The first screenshot immediately bought some interest as it was using custom segments. I liked the custom fence segment in front of the door leading outside and was the door at the top of the ramp meant to be blocked up with wood? If so, I think you should add another bit of wood-one at the top of door and one at the bottom.
The second screenshot gave a nice outside view of the castle(I presume it is a Castle?), and the railings along the top gave it a nice castle feel imo. Overall, it was a good screenshot as it portrayed a castle feeling whilst keeping framerate around 32.
In the third screenshot, I liked the railings in front of the door, but, if possible, I think it would look better if it covered the whole door like one of those old days castle gateways. The water looked a bit strange, but I don't think you can help that anyway. The waterway end being blocked off gave it a nice feel.
The fourth screenshot was very intrigueing and the pool with ramps and stairs was very well set out. Good job!
